How Long Does a Water Heater Last? - Service Plus Heating, Cooling & Plumbing
Water heater age

We take hot water in our home for granted until the water heater goes out – then comes the decision of repairing or replacing it. Repairs will probably be fine if your unit is only a few years old. If it’s older, it may be time to replace it. But just how long should a water heater last?

Age alone isn’t always the issue – maintenance history, water quality, and usage can affect how long a water heater will last. The type of water heater also plays a part. Many factors affect the life expectancy of a water heater, but it’s essential to recognize the signs of aging and other outside factors that can affect it.

Tank Water Heaters

A traditional tank water heater can last 8 to 12 years on average. The interior is protected by an anode rod that attracts corrosive particles. Once the rod has corroded too much, particles can settle in the bottom of the tank and build up over time, destroying the lining. If your water heater is rusting on the inside, you may begin to hear it gurgle, and it may be time for a new one.

Tankless Water Heaters

On-demand water heaters do not constantly work to supply hot water, which makes them last longer than traditional tank water heaters. Tankless water heaters can last nearly 20 years or longer. However, tankless water heaters can also rust on the inside and require replacement.

Finding the correct water heater can be difficult, so let Service Plus assist you in selecting the right one for your home. We will help you find the best size and most energy-efficient unit for your home so you keep plenty of hot water without breaking the bank.
